To all whom it may concern:

Be it known that we, Enmnn E. HENDER- war and GEORGE Aroma, citizens of the United States, residing at Lebanon, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Means for Attaching Points to Pools; and we do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

Our invention-relates to new and useful improvements in means for attaching points to picks or other form of tools and our object is to provide means for removably securingthe points in osition.

A further 0 jeet is to rovide means for reinforcing the points, w ereby the strength thereof will be equal' to the strength of a point formed integral with the tool and a still further object is to provide means for locking the point in position on the tool.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this ap lication, Figure 1 is an elevation of a pick showing our improved attachment applied thereto. Fig. 2 is a de tail perspective view of one end 'of the pick with the-point removed. Fig. 3 is a. perspective view of the device adapted to cooporate with that end of the pick shown in Fig. 2. Fig. 4 is a perspective view of the opposite end of the pick, and, Fig. 5 is a perspective view of the device adapted to cooperate with that end of the pick shown in Fig. 4.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a pick head, which terminates on opposite sides in tines 2 and 3, this form of tool being particularly a plicable in mining and railroad work, in which one of the tines is employed for digging, while the opposite tine is employed for tamping purposes and to this end a sharpened point 4 is secured to the tine 2, while a tamper 5 is secured to the tine 3. l

The outer endof the tine 2 is rovided with a channel 6, theside walls of w ich converge towards the closed. end of the channel and in this channel is adapted to be seated a shank 7 carried by the point 4}said shank being likewise tapered to fit the converging walls of the channel 6 and as'the oint, when in use, is more or less dragged t rough the.

earth, thereby cousin 0. rearward strain on the point, the side an end walls of the channel 6 are provided with ribs 8', which are wal s of the shank 7, the ribs on the side walls extendin longitudinally of the channel, and the ril) across the end wall of the channel connecting the two side ribs.

The head 4 extends to each side of the shank 7 to form shoulders 10, which shoulders are ada ted to engage the end of the tine 2 at eac side of the channel 6 and extending at right angles from the longitudinal plane of the shank 7 and integral with the shoulders 10, are ribs 11, which are adapted to engage seats 12 in the end of the tine 2 and by arranging the ribs and their respective seats in the manner shown, the greatest strength is opposed to the point of greatest strain.

The point 4 is fixed to the tine 2 in any preferred manner, as by introducing a locking bolt 13 through alining openings 14 and 15 in the tine 2 and shank 7, one end of the opening 14 in the tine 2 being threaded to receive the threaded end of the bolt 13 and as said bolt extends laterally through the tine 2 and the interposed portion of the shank 7, it will be readily seen that said point will be securely locked in osition on adapted to enter seats 9 in the side and end the tine, and if desired, any suita )le form of wedge (not shown) may be introduced in alining recesses 16 and 17 in the tine 2 and shank 7, respectively.

When the pick is used for tamping purposes, the major portion of the strain is directed longitudinally of the tine and in securing the tamper thereto, the ribs 18 are extended transversely across the shank-19 and the seats 20 in the walls ofthe channel 21 are likewise extended vertically of said channel instead of longitudinally thereof, the shank in this instance being entered in the channel by placing the shank above the channel and moving the same downwardly and by inclining the ribs 18 and the seats 20, the shank 19 will gradually move towards the closed end of the shank 6, as the shank is lowered into the channel, the ribs 22 on the shoulders 23 of the tamper 5 entering seatsas PATENT oFFicE..t-, f

a. sufiicient distance to bind the ribs 22 on the end of the tine 3. After he shank has been seated in the channel 21, a bolt 25 is entered through re istering openings 26 and 27 in the tine 3 an shank 19, respectively, thereby securely holding the tamper into engagement with the tine. f It will be clearly understood that while we -,have sh'own the point and tamper as used in connection with a pick, said parts may be used in connection with any suitable form of tool or im lement and when the tool is to be given a strain, the ribs and seats are to be construct 15 ed as shown in Fi s. 4 and 5, out when the strainis directed ongitudinaliy of the im plement, the ribs and seats are to be formed as shown in Figs. 2 and'3, thereby opposing the greatest strength of the implement to the 20 point of greatest strain. It will likewise be seen that the points may be readil and quickly attached or removed'from t e implement and that said parts may be cheaply constructed and further that by remove 1y 25 attaching the points to the tines of the imlement, said points may be removed and an additional point attached theretopwhereby the im lement may be continued; in use while t e extra points are being sharpened.

tagging movement or a lateral' What we claim is: 1. The combination with an implement having a channel therein; of a removable part ada ted to be secured'to said implement, as ank on said removable part adapted to fit said channel, cooperating ribs an seats in said channel and shank, which ribs and channels are opposed to the greatest strain on the implement and parts-attached thereto and means to fix the removable part to the implement.

2. 1311 attachment for an implement of the class described, com rising the combination with the implement aving a channel therein, the walls of which are tapered; of a removable point for said implement, a tapered shank on said point adapted to enter said channel, interlockin ribs and seats for said 1m lement and Shitlfii and a bolt adapted to .100 said shank in said channel.

, In testimony whereof we have signed our names to this specification 111 the presence of two subscribing witnesses. 4
